Séminaire de Géométrie

The Thurston spine of the genus 2 Teichmüller space

Ingrid Mary Irmer (Shenzhen)

Salle 2

In the 80s, Thurston gave a controversial construction of a mapping class group equivariant deformation retraction of the Teichmueller space of a closed, compact surface onto a lower dimensional spine. This talk will review Thurston's construction and related questions. The results of a computation in genus 2 will be presented, resolving many of these questions in genus 2.
